SD card cannot be used - update to 4.2?

Hey guys!

So, I began at the weekend to softmod my 3.4 UK PAL wii...

I copied the mod files to a 4gb genuine Ultra III Sandisc SD card. However - I could not use that SD card. The wii told me something like "the device in the sd card slot cannot be used". I have read because of the older FW it cannot read an SD card bigger than 2.0GB?

Anyway... I would like to update to 4.2FW so I can use my 4GB SD card. Is this possible? I understand I cannot do an online update as it will update me to 4.3 which is useless atm.

You are going to need New SUPER MARIO BROS. Wii to update to firmware 4.1. There are many other games that contain firmware 4.0, 4.1 or 4.2. Just try inserting all games you have and see if it lets you update. No games contain firmware 4.3 so far, so don't worry about that.
